CHARLES W. BAKER, OF PAW PAW, MICHIGAN.

TACKLE.

Specification of Letters Patent.

Patented Nov. 10, 1908.

Application filed December 16, 1905. Serial No. 292,015.

To all whom it may concern:

Be it known that I, CHARLES W. BAKER, a citizen of the United States,residing at Paw Paw, in the county of Van Buren and State of Michigan,have invented certain new and useful Improvements in Tackles, of whichFurtherobjects, and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which Figure 1 is a side elevation view of my improvedtackle. Fig. 2 is an enlarged detail view, showing the arrangement of myimproved rope gripping or locking means. Fig. 3 is a detail transversesectional view taken on a line corresponding to line 3-3 of Fig. 2,looking in the direction of the little arrows at the ends of the sectionline.

In the drawing, similar letters of reference refer to similar partsthroughout the several views.

Referring to the drawing, the pulley blocks A A are preferably providedwith tapering side plates and pulleys of varying diameters arranged inseries therein as is illustrated in the drawings.

In the structure illustrated A is a running block and A is a fixedblock, the load being secured to the running block by means of asuitable rope as G, or otherwise as desired. One end of the tackle ropeB is preferably secured to the running block -A, as illustrated, and isthence rove over the sheaves, first over the inner sheaves and thence tothe outer sheaves of the blocks, with the hauling end of the ropehanging from the fixed block. On the side of the block A is a laterallyprojecting fixed jaw a. The face of this jaw is curved transversely toreceive the rope,-see Fig. 3.

A pivoted jaw a having a longitudinally curved and toothed or serratedgripping face is pivoted on the side of the block A and arranged tocoact with the jaw 64 in gripping the rope,-see Figs. 1 and 2. When thejaw a is in its lower or normal position, the rope may be easily placedbetween the jaws, when by swinging the pivoted jaw up until it contactsthe rope, it will automatically engage the same by allowing a slightbackward movement thereof. To release the rope it is only necessary topull downwardly thereon, which causes the jaw to release and drop to itsnormal position, against the projecting journal bearing a which servesas a stop therefor; releasing the rope so that it may be manipulatedindependently of the jaws.

It is evident that the load can be locked or held in any desiredposition and that the lock can be quickly released and the tackle usedindependently of the lock, without the necessity of adjusting or lookingany parts to prevent their engaging the rope.

I have illustrated and described my improved tackle in the formpreferred by me on account of its structural economy and conveniencewith which it may be used.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a tackle, the combination of a pair of pulley blocks; a tacklerope rove therein;

a laterally-projecting fixed aw having a groove-like engaging face onthe outside of the running block; a aw having a longitudinally-curvedengaging face with forwardly-projecting teeth pivoted on said runningblock and arranged to coact with said fixed jaw in grasping the fall endof the rope whereby the fall of the rope may be entirely freed from saidjaws or engaged as desired; and a supporting stop for said pivoted aw.

2. In. a tackle, the combination of a pair of pulley blocks; a tacklerope rove therein; a laterally-projecting fixed jaw on the runningblock; a jaw having a longitudinallycurved engaging face withforwardly-proj ecting teeth pivoted on said running block and arrangedto coact with said fixed jaw in grasping the fall end of the ropewhereby the fall of the rope may be entirely freed from said jaws orengaged as desired; and a supporting stop for said pivoted jaw.

3. In a tackle, the combination of a pair ning block; a jaw pivoted onsaid running i of pulley blocks; a, tackle rope rove therein; alaterally-projecting fixed aw having a groove-like engaging face on theoutside of the running block; a jaw pivoted on said running block andarranged to coact with said fixed jaw in grasping the fall end of therope whereby the fall of the rope may be entirely freed from said jawsor engaged; and a supporting stop for said pivoted jaw.

4. In, a tackle, the combination of a pair of pulley blocks; a tacklerope rove therein; a laterally-projecting fixed jaw on the runblock andarranged to coact with said fixed jaw 1n grasping the fallend of the 1'0e 15 'whereby the fall of the rope may be entire y CHARLES W. BAKER.
